AIRTIGHT CONTAINER

摘要

An airtight container comprises a receiver, a cover and a sealing ring. The cover comprises an opening. The sealing ring is used to block a gap between the cover and the receiver when the cover is used for closing or sealing an inlet of the receiver. A valve part is used to close or seal the opening. The valve part comprises a tunnel and a valve to close or seal the tunnel. The valve extends from the valve part into the tunnel and has a thickness decreasing from the valve part to a center of the tunnel so as to form a concave surface at a side of the valve facing away from the tunnel. The valve can be opened by air leaving the receiver.
